Six transformations, one pot: Various di- and trisubstituted vinyl triflones, as well as several heteroaryl triflones, were stereoselectively synthesized from easily accessible gem-dibromovinyl substrates (see scheme, Boc=tert-butoxycarbonyl). The highlights of this synthetic method lie in the remote O→Cvinyl or N→Cvinyl triflyl migrations and the one-pot, three-step protocol.
